11 Claims.

This invention relates to hot stamping devices particularly adapted to cut out monogram-forming type.

The object ofthe invention is to provide a simple and efiicient machine which, with very little instruction, canbe used .byany operator for the purpose of stamping monograms into letterheads or similar uses, and preferably to do this any color compared to the color of the paper to which the monogram is applied can be used. The invention has for. its object to provide an improved means for holding the type during its operatiomwhich however isvvery simple in operation :to permit the hot type to be discharged therefrom, to enable interchange type to be used for the next monogram.

Theinventionalso has for its-object to provide a simple and efficient means for holdingthetype which is'hiddenfrom view of a bystander but is capable of being utilized by the operator when using the machine.

For these purposes, the invention consists of a hot stamping device especially'adapted for outout type in which a novel chasesupports the type and permits it to be released therefrom, and which chase is brought into position 'for stampingoperation by a very simple operation.

The invention consists further in the arrangement of the type holding tray below the body of the machine whereby it is out of view when not used and is within the scope of the work of the operator when being used andaway from any bystanders.

The invention consists further in the novel arrangement of parts necessary to carry out the stamping operation.

The invention consists further'in certain combinations of parts, embodiments of which are shown in the accompanying drawings and which will be described hereinafter and finally pointed out in the claims. I I

Similar characters of reference indicate corresponding parts throughout the various views.

Referring to the drawings, andmore particularly to Figures (i -to 9, wherein the type and the type holding case are shown, the type used in the hot stamping machine forming the invention of this application, is a'cut-out monogram type. In Figure .7, a side view of the typeis shown by I2 having the sharp and very narrow poj'ections I3 forming portions adapted to cut out paper so as to provide perforations in the letterheads, the letters forming the monogram of aietterhead being in outline form with the parts of the letter paper cut away so as to form outlines of the initial against the background of the paper itself. These type have the projections I3 in very sharp contour. Interposed between the type are the usual spacers such as used in printing indicated at I4, and these types; necessary to form the adaptedmonogram and'the spacers are loosely held in a type case I5 shown in perspective in Figure 9. This type casing I5 is supported upon the body portion of a chase I6 and the type casing I5 is adapted to be placed upon the said ,body portion between two oppositelydisposed spring actuated walls I1 and I8. The wall I1 is formed as part of the movable shaft I9, which passes through the trunnions 2'0 and has at its exterior end a knob 2|. Around the movable shaft I9 is a cap portion 22 which embraces the free end of a shaft I9 and which is secured to knob 2| by means of a screw 23. At one side of the trunnion 20 a member having a recess 25 is placed, and within the recess one end of a spring 26 is seated, the other end of the spring 26 acting against one face of the wall I1.

The normal tendency ofthe spring 26 is to force the wall member I! inwardly, and when the knob 2| is pulled outwardly towards the left of the prong shown in Fig. 7, the wall member I I1 is moved, therewith andcompresses the spring 26. The right hand of Fig. 7 shows a similar structure in all the parts described operating in the same way, but in this casethe shaft I9 has a stubbed projection 21 adapted to enter an opening 28 in the end wall of the type casing I5. This type casing I5 is provided with a similar opening 29 at its other side so that no matter in what position the type casing I5 is inserted between the walls l1 and H3, at least one of the openings either 28 or 29 is engaged by the stub projection 21. The function of the projection 21 is to enter one of the openings 28 or 29 and thus hold the type casing in position.

In Figure 8, there is shown a position of the type casing I5 as held in position by the action of the oppositely disposed pressure members l9 and I9 with the stub 21 engaging the opening 28 of the casing, and also exerting a pressure upon the types and spacers within the casing. It is in this position that the type is used to cut the monograms in the paper, when the type is brought into stamping position. When it is desired to permit the type to fall out of the casing IS, the knob 2| is pulled outwardly a slight distance to release the stub 21 from pressure upon the type whereupon the type can fall out of the casing. If it is desired to release the easing l5, the knob or knobs 2|, 2| are pulled out slightly further to disengage the stud from the opening 28, and to disengage the pressure. of the wall members H and Hi from the end walls of the holder l5, whereupon the holder can also drop out by gravity. The action of the knobs 2| and 2| has been described as operated by hand. This action can also be brought about by automatic means, in that supporting rails 30 for'the' chase are arranged parallel to each other having guideways 3|. Wedge shaped members 32 serve to press the knobs 2| and 2| outwardly, whereby the pressure on the type and casing is released and the type and spacers may be taken out of the chase, and other type and spacers substituted. If desired, the casing i5 may also be removed. The drawing of Figure 6 shows a top view of the parts described, with all of the type facing vertically upwards for insertion and removal.

Figures 3 and 5 show side views of the chase rails 30 and guideways 3|, and the wedged shaped members 32. The chase I6 is provided with a cylindrical extension 35 having a groove 36, which is adapted to fit into a locking device in the member 34 of the machine, which locking device consists of a spring actuated pin 31 fitting into the groove 36 when the extension'member 35 is inserted into the bore 35 This serves to temporarily lock the chase in position, so as to hold it during the stamping operation, as shown in Figure 5. The chase is provided with rollers 38 on each side thereof to engage with the guideways 3|. Normally the chase is in type-up position as shown in dotted lines in Figure 5 for the setting of the type; thenit is moved from the position in dotted lines to the position in full lines in Figure 5, in position for the stamping operation, the movement being along the guideways 3|. The chase, as shown in Figure 2, is provided with a V-shaped recessed portion 40, adapted to engage a correspondingly shaped downwardly projecting member 4| on the press so as to lock the parts together for the stamping operation.

When the chase reaches the position shown in full lines in Figure 5, its rollers have left the guideways 3|, since these terminate, and since the chase is guided by the wedge shaped members 40 and 4 The chase is operated for its stamping operation by any suitable press. In the embodiment, the standard 46 of the machine is provided with a bore 41 in which a plunger 48 moves Ver ically upwardly or downwardly, this plunger being operated by a pivoted link |8 pivoted also at 49 to lever 50, pivoted at 5| to the standard 43, which lever 50 is in turn operated by a hand lever 52. The downward movement of the plunger 48 moves the chase support and chase downwardly for its stamping operation.

Beneath the plunger 48 is a table 53, under which a type holding tray 54 is placed which is guided drawer-fashion in the guideways 55 extending from the lower surface of the table. The tray is shown in extended open position in Figure l, in plan view, in end view in Figure 2, in end view in Figures 3 and 5. The tray has arranged thereon suitable holding devices to en.- able the types to be alphabetically disposed there-- in with a supply of spacers, and if desired, a few extra type holders like that shown in Figure 9, to replace the hot one. Also, if desired, a plurality of type parts may be used. The advantage of having the type tray below the table is that it is readily accessible to the operator, and out of the way of the inquisitive bystander who is likely to play with the type or take one or more out of the tray and then misplace it on returning it. Also, when the hot type drops out upon the table, it is most readily separated and placed in its proper position in the tray.

The table 53 has a cut-out portion 56, which is preferably filled in by a fiber plate 51, so that when for any reason the paper to be stamped and its backing do not sufficiently break the force of the type, the type is not forced full force against a hard metal surface such as is used for the table. 1

The paper to be stamped may also be coated with a silver or gilt or other colored finish and for this purpose a supply roller 58 suitably supported on a shaft 59 is in turn supported by a part of the frame or standard of the machine{ and this colored strip 59 then extends over a spring actuated roller 50, also supported on the frame of the machine, and'then passes below the sphere of influence of the type of the chase; then over a similar spring actuated roller 6|, and then over a clutch rol1er'62 supported to the frame of the machine, which clutch roller 62 has a spring actu ated lever 63 with a roller 64 presslngon the strip passing over the roller 62, all as shown in Figure 2.

To serve as a soft backing for the colored strip, another strip 64 of fiber-like material passes from the supply roller 65 over a roller 66, then across the sphere of influence of the type and then over the roller 61 to the clutch roller 62, all as shown in Figure 2.

The paper to be stamped is placed on the table 53 as shown in Figure 1 and to facilitate accurate stamping, gauges are provided against which the papers may be placed. 0ne such gauge 68 is at the rear of the table 53, and is regulated by set screws 69, and is parallel to the front of the machine; and another gauge 10 substantially vertical thereto regulates the side of the paper to be stamped and is held in position and regulated by set screws 1|.

The operation is as follows:

The type is selected and then after the casing has been placed into the chase, the type and spacers are placed into the casing, when the chase is in the position shown in dotted lines in Fig. 5. The current is then turned on and'the heating element serves to heat the type. The chase is then moved in its guideways from the position shown in dotted lines in Figure 5 to the full line leased and the parts return to type brought down against the colored paper, this against the paper to; be stamped, and all against the fiber backing strip; and against the platen of the fiberfuntil the stamping of the monogram is completed, when the handle is re-- their initial position by't-he action-of the springs '55.' The chase with itstype is usedas often as desired, the chase "remaining in its position as shown in full lines in Figure 5.

When a new monogram is desired, the chase is moved on its guideways to the dotted line position as shown in Fig. 5, and the new type and spacing can be inserted upon the removal of the old, by means of tweezers or the like, in view of the heated condition of the type. Or the chase can be moved to about a position directly below the dotted line position, but in upside down position and still on the guideways, and by normally pulling outwardly the knobs 2| and 2%, either the type first or then the casing l5, or both can be dropped out by gravity. The chase is then moved up to the dotted line position in Fig. 5, and a new casing and a new type, as the case may be, can be inserted.

The paper to be stamped canQif desired, be provided with a colored background at the place where stamped which then provides a two color eifect.
